pylab_examples::date_index_formatter Namespace Reference

Detailed Description

When plotting daily data, a frequent request is to plot the data
ignoring skips, eg no extra spaces for weekends.  This is particularly
common in financial time series, when you may have data for M-F and
not Sat, Sun and you don't want gaps in the x axis.  The approach is
to simply use the integer index for the xdata and a custom tick
Formatter to get the appropriate date string for a given index.
